What is the best fluid for resuscitation after a burn?

• A. Lactated Ringer's
• B. Normal saline
• C. D5W
• D. Colloidal solution

Answer: (A)

In burn resuscitation, the goal is to rapidly restore intravascular volume while avoiding worsened acid-base balance. Lactated Ringer’s is the best choice because it is a balanced crystalloid with electrolyte content close to plasma, so it effectively expands the circulating volume without causing large chloride loads. The lactate in LR acts as a buffer once metabolized to bicarbonate, helping counteract acidosis that can accompany severe burns and hypoperfusion. Dextrose-containing fluids like D5W are not ideal for initial resuscitation because the dextrose is quickly metabolized, leaving free water that can dilute sodium and worsen edema or hyponatremia. Large volumes of normal saline can contribute to hyperchloremic acidosis and edema due to excess chloride. Colloids aren’t typically used in the first 24 hours of resuscitation because they don’t reliably improve outcomes during the capillary leak phase and can add cost and risk; they may be considered later once capillary integrity begins to stabilize.
